A KBS-produced 3D medical documentary is being shown at movie theaters.

The documentary “Fetus” reveals the mysteries of birth in 3D images.

It won an award at a film festival last year for its excellent 3D technology.

The production of the documentary took two years and cost 400 million won.

Its vivid, realistic images were acclaimed when it was aired on TV.

The documentary is being screened at five movie theaters. But the number can increase to 130 if viewer responses are good.

Experts say that with the TV broadcast produced in higher, refined quality, the boundary between TV programs and movies has begun breaking down.
